The magnetic field intensity generated by a pair of magnetic poles does not decrease with the increase of the distance from the magnetic pole, but only changes the distribution state with the existence of paramagnetic substances in the magnetic field. The vacuum will not affect the distribution and intensity of the original magnetic field. How much electric energy does it take to use electromagnet...
Powerful magnet is widely used in life. It is a high-tech material in the National 863 project, which belongs to a high-end rare earth material. In medical treatment, Nd-Fe-B has been widely used in physical magnetic therapy. Maybe we don't know much, because magnets are usually packaged by other forms of products. For example, headphones, stereo, antenna, mobile phone leather case, antenna, compa...
Ring magnet magnetized in Radial Direction is developed successfully which is using shaping method by new multipole radiation rientation, and meet different requirements of permanent motors. Fundamentally changed the past situation that radial ring magnet only relied on the magnetic tile assembly, greatly improve the performance of the motor. The popular poles include: 2 pole, 4 poles, 8 pole...
The development of elevator has brought great convenience to contemporary people's life, so the electromagnet of elevator lifting equipment is its main part, that is, crane. Lifting machinery is an indispensable equipment for modern industrial production, which is widely used in the lifting, transportation, loading and unloading, installation and personnel transportation of various materials. Cran...
Easy to use and cost effective Flexible magnet is a cheap extruded permanent magnet. They can be use in products such as flexible magnetic strip, magnetic sheet and label magnet. Flexible magnets can be bent, cut, twisted, crimped, printed, screen printed, decorated or marked with scissors or knives, permanent or erasable marks, etc. We have a wide range of magnetic wall coverings for homes,...
1. Alnico Magnet :is made of aluminum, nickel, cobalt, iron and magnetic materials cast and sintered at 600℃. Aluminium-nickel-cobalt magnets are more expensive than iron oxide, and cobalt is scarce. Alnico magnets are the earliest magnets used in trumpets, such as trumpets (known as tweeters) in the 50s and 60s. Generally made of internal magnetic horn (external magnetic type is also available). ...
Rubber coated magnet is to wrap a layer of rubber on the surface of the magnet, which is usually composed of sintered neodymium iron boron (strong magnet), magnetic conducting iron sheet and rubber shell. This structure can avoid damage and corrosion. The rubber coated neodymium basin magnet is a rugged magnetic component with a threaded center hole (internal thread) and a protective rubber coatin...
The neodymium iron boron magnets are currently recognized high-performance and cost-effective magnets in the magnetic material industry. Many high-tech fields have designated them to make various parts, such as national defense military, electronic technology, medical equipment, Electrical machinery and other fields are involved. The more it is used, the easier it is to find the problem. Among the...
With the development of The Times, all kinds of new things appear in our life and work, thus bringing a lot of convenience to people, especially with the development of science and technology, all kinds of science and technology emerge in our life. Such as the use and function of magnets, this small tool for life has brought many uses and function. Magnets are widely used, such as Magnetic Holder,...
Because the weak stray magnetic field interferes with the aircraft's navigation system and control signal, the International Air Transport Association (IATA) lists magnetic goods as class 9 dangerous goods, which must be limited during collection and transportation. Therefore, now some air cargo with magnetic materials need magnetic testing in order to ensure the normal flight of the aircraft. Mag...
